svelte-kit dev and svelte-kit preview are used for development and debugging purposes and should not be run for production builds.

when deploying to a server you run svelte-kit build to generate the final site (in your case that should be located in ./buildit)

i don't think that you can statically specify the port being used, but you can provide it when launching the server using an environment variable.

(i am using @sveltejs/adapter-node, so this might be different for other adapters)

It appears that this was a known configuration issue on Stripe’s end and a fix was deployed. You shouldn’t be seeing these errors anymore. From what I can tell from Stripe’s discord server threads regarding these errors, r.stripe.com is just for tracking metrics so it should not have any impact on the ability to make payments.

CSP setup for Stripe Integration

Asked 2022-Feb-15 at 20:34

I have a stripe elements integration on my project. I use sapper on front end and ruby on the backend.

I followed the tutorial to setup the server to generate payment intent using stripe private key and front end to show stripe embeddable UI using stripe publish key, everything works fine the only problem is as follows.

Once a payment is done using test card details I get the following error Refused to load the image 'https://hooks.stripe.com/img/favicon.png' because it violates the following Content Security Policy directive: "img-src data: https://q.stripe.com".

ANSWER

Answered 2022-Feb-15 at 20:34

The issue that you describe is related to the CSP and how it is configured for your project. Stripe has documentation related to the CSP describing all the required directives https://stripe.com/docs/security/guide#content-security-policy. It requires img-src directive to allow loading of the content from https://*.stripe.com while your current directive permits only data: and https://q.stripe.com. Extending your current directive with the requirements from Stripe should solve the issue.

QUESTION

vercel published sveltekit where vite fails to register serviceworker placed in src folder

Asked 2022-Feb-11 at 22:40

This question will need someone from vercel team or sveltekit team as it is related to pwa app that I published to vercel: 1- I placed a minifest1.js file in the "static" folder 2- I placed testserviceworker.js file in the "SRC" folder.

When I run my app locally using my laptop by "npm run build" and "npm run preview", vite registers my serviceworker, my cache is populated and the app is installable as pwa.

When I deploy the same code to vercel, vite fails to register the serviceworker. To experiment I added the serviceworker file to the static folder and added a register button in index.svelte to register the file manully when I press the button.

When I press the button, the serviceworker is registered, I'm able to verify it in dev tools, application tab, cache and able to install my app but my lighthouse report showing pwa part as failed.

So my question is regarding vite registering serviceworker by default upon starting the site. Do I need to add a function in load or onMount with "navigator.serviceWorker.register('testserviceworker.js" or there is some kind of magic configuration in vercel or svelte.config.js to point vite to where the serviceworker.js so it register it upon starting the app?

I added the files for manifest and serviceworker here but I don't think they're relative to my question as it is a configuration issue not code issue:

Answered 2022-Feb-11 at 22:40

I found a solution. I had to create a @lib folder in the src/node_modules folder and there file eg. db.js. In that file instead of import you need to use require()! and then you have to export the function that connects to the database. and then you can import that in the path

There is a problem with your input shape obviously.

The architecture of your model is as below. So the input shape should be (1,400,400,3).

In the function prepare that feeds the data to the network, the output shape is (400,400,1). And that is why you get an error.

registering socket IO to vite for sveltekit

Asked 2021-May-20 at 08:12

I have written a few apps using svelte and sapper and thought I would give sveltekit a go. All in all it works, but I am now running into the issue of registering a worker on ther server.

Basically I am trying to add socket.io to my app because I want to be able to send and receive data from the server. With sapper this wasn't really an issue because you had the server.js file where you could connect socket.io to the polka/express server. But I cannot find any equivalent in sveltekit and vite.

I experimented a bit and I can create a new socket.io server in a route, but that will lead to a bunch of new problems, such as it being on a separate port and causing cors issues.

So I am wondering is this possible with sveltekit and how do you get access to the underlying server?

...

ANSWER

Answered 2021-May-20 at 08:12

You cannot connect to a polka/express server because depending on the adapter you choose there can be no polka/express server used - if you deploy to a serverless platform for example. Sockets for serverless are not so easy to implement and their implementation depend on the provider.

You are raising an important concern but right now I'm afraid this is not possible - someone corrects me if I'm wrong.

What you still can do is to write your front with SvelteKit, build it as a static/SPA/node application and then use your build from your own polka/express server. You lose the swift development experience offered by SvelteKit though, since your development will be parted in two: first the client, then the server.

SvelteKit split second unstyled html

Asked 2021-Apr-10 at 09:56

I created an base app though the sveltekit cli commands. The options I chose are scss and typescript. At soon as I started the application for a split second I saw unstyled html. This happens every time and with every project i create. I did some testing and it seems like the css(app.scss) is loaded after the html(localhost). Another this that seems consistent is that is happens every time i reload the page, but not with navigating. This indicates that it is probably server-side. In my mind the html and css should load in the same file, though SvelteKit might have a different approach.

I had the same issue with Sapper and solved that. But I forgot how I fixed it. Also with the new SvelteKit setup many things are different. Do you guys know how to fix this?

Thanks in advance

ANSWER

Answered 2021-Apr-10 at 09:56

SvelteKit does not bundle everything together during development mode and injects support for HMR. This may result in flashes of unstyled content.

The flashes of unstyled content should go away in production mode, when you deploy with an adapter.

This stock SvelteKit template does not flash unstyled content. The only change was changing the adapter from the node adapter to the static adapter so it could be hosted on Netlify. (I have also confirmed with the Netlify adapter, so it's not a difference between static and dynamic.)
